Electromagnetic cradle

Abstract

The invention discloses an electromagnetic cradle. The cradle swings left and right under the intelligent control by a principle that the like poles of electromagnets are repelled, and the unlike poles of the electromagnets are attracted, and the amplitude of swing is controllable by means of program feedback regulation. The electromagnetic cradle is controlled by an acoustic control mechanism, is automatically started when an infant cries, is similar to a cradle mutually operated and cannot generate additional pressure on cardio vessels and cerebral vessels of the infant; the electromagnetic cradle does not have noise when operated and provides a quiet place for the rest of the infant; the outer side of a cradle body is coated with aluminized or galvanized sheet iron plates; and an additional electromagnetic shielding net is formed by braiding thin metal wires, and a layer of mosquito net is decorated on the outer surface and is aesthetic and practical. The electromagnetic cradle effectively prevents unnecessary damage caused by electromagnetism radiated by household appliances to babies, is simple in structure and convenient to use, adopts safe voltage, saves electricity, cannot produce potential safety hazard and builds a safe and comfortable environment for the infants.

Description

technical field [0001] The invention relates to a cradle used in the daily life of infants, in particular to an electromagnetic cradle. Background technique [0002] Babies who are not yet born often lie on the cradle to sleep. The drive of the cradle requires the parents to shake it all the time to keep the cradle shaking. This consumes a lot of time for the parents and is also a test for the parents' physical strength. Existing electric cradles are mostly driven by motors, and the cradles are mostly shaken up and down or back and forth, and seldom shake from side to side. In the process of shaking back and forth, additional pressure will be generated on the cardiovascular and cerebrovascular, and the size of the additional pressure is related to the shaking speed, which is not good for the growth and development of the baby. This additional pressure should be reduced as much as possible. In addition, the baby is driven by a motor, and the motor is installed on the cradle,...

AI Technical Summary

Problems solved by technology

But it has many problems: one, the period is different when the swing amplitude is different, so the change period of the electromagnet polarity is not easy to control, and is constantly changing; Power supply, high voltage is not safe for babies. If a low-voltage power supply is used, the frequency conversion of the power supply is required when stepping down, which is difficult to meet the needs of the swing cycle of the cradle. Third, the swing amplitude is uncontrollable. It is getting bigger and bigger, and the self-starting of the cradle is unstable; Fourth, the constantly changing strong electromagnetic field is likely to affect the development of the baby within a short distance
